IMPROVEMENT IN COMBINED LETTERSHEETS'AND ENVELOPES.

` i Specification forming part of Letters Patent No. 150,390, dated May 5, 1874; application filed April 8, 1874.

To all whom t may concern:

Be it known that I, WILLIAM B. BARY, of Detroit, Vayne county, Michigan, have invented a Combined Letter-Sheet, Envelope, and other devices, as set forth herein, of which the following is a speciiication:

A letter-sheet and envelope combined, with printed or written business-cards, and time and dat-e dials thereon, are shown in the accompanyin g drawings, and described as follows,viz:

In Figure 1, the heavy black lines d a au represent the form of the sheet and envelope 'iin-p, which may be single or double sheets.

rlhe lightii'n'esb b b represent the folds in the The dotted lines c c c c represent perforations in the paper, for convenience in opening the letter and detaehing the business-card. g g g represent the envelope-flaps, which are gummeid upon the reverse side, and when the letter is closed the end iiaps g g are brought over and adhered to theface side of the letter. d is the business-card of the writer, for convenience in liling the letterobviating the necessity of writing naine and residence thereon, thereby preventing mistakes in filing. E represents dials, indicating hours oi the day, days of the week, the months, and days of the month and year, by means of which, properly underscoring the figures and words, the exact time of receiving and answering the letters can be instantaneously and permanently indicated thereon. These dials are shown upon a larger scale in Fig. 5. f, surrounded by perforations c c o c, represents a space upon the iiap g,for the business-card of the writer, which, being gummed upon the reverse side, can be detached and adhered to the face side of the answering letter for a direction, thereby guarding against mistakes in the direction thereof.

Fig. 2 shows the sheet folded, ready to be closed by the flaps g g g. Fig. 3 shows the end flaps g g closed upon the face side of the letter.

I claim as my improvement- As a new article of manufact-ure, a lettersheet adapted to be folded in its longitudinal center, one. end of which bears a printed indicator for date and time, and having combined with it a main sealdiap, g', perforated for ready separation, and carrying a detachable gummed address-label, the whole so shaped as to be folded into theform of an envelope and sealed by means of auxiliary iaps g g. i

In testimony that I claim the foregoing I have hereunto set my hand this 8th day of April, 1.874.
